Does anyone know which colours were used for painting the English buildings in the photos in the Baccus catalogue?  In particular, I'd be interested in knowing which shade was used for the stonework on the church

Whattle and daube (the bits between the wood) would be off white/ very light brown, the wood will be brown or grey brown, any weathered wood really not black (Victorian ). Brick tended to be red/brown or possible grey blue. Churches will be sandstone red brown or granite green grey like the local churches. If it's Ecw your doing remember it's pre industrial revolution so less blackening. Look at the images for the Weald and Downland museum site.

Thanks very much Tim.  I don't think that my painting does these lovely models quite justice, but they do look quite good now.  I think the church is a beauty.

Don't let me see them as I like painting buildings and I don't need more

Limestone was also used for building churches, which is generally a lightish grey/off-white colour. As above, don't paint half-timber houses black and white; this is very much a modern phenomenon. Natural wood tends to age to a grey colour. Wattle and daub can be painted buff or very pale yellowish brown. Also remember that thatch very quickly (a few months) weathers to grey, then stays that colour 'til replaced 50 years later.
